I'd like to back up the full app data of at least three of my games (complete with game progress) and transfer them to my brother's iPhone.

We are syncing both mine and his iPhone to the same computer. My idea is to use iTunes backup but Apple is very scarce when referring to what iTunes backup does - support.apple.com/kb/ht4946. iCloud backup is also a bit lean on what app data is included in the backup - support.apple.com/kb/PH12519.

What app data is exactly being backed up by iTunes and how can I select which games (along with game saves) to restore to my bro's iPhone? Thanks for your attention.
